Annular Pancreas is a congenital (birth) defect in which a ring of pancreatic tissue encircles and may constrict the duodenum (the first part of the small intestine). This abnormal ring can block or narrow the intestine, leading to feeding and digestive issues in newborns and gastrointestinal symptoms in older children or adults.
Symptoms can vary by age but often include:
This condition develops during fetal growth when the pancreas normally forms from two separate buds that should fuse and rotate away from the duodenum. In Annular Pancreas, the rotation process goes awry, causing pancreatic tissue to wrap around the intestine rather than moving to its usual position.

Annular Pancreas is typically diagnosed using imaging studies such as a CT scan or endoscopic ultrasound. In some cases, an MRI, abdominal ultrasound, or upper endoscopy may also be used to confirm the presence of the pancreatic ring around the duodenum.
Mild cases of Annular Pancreas that do not cause significant blockage or symptoms may be managed conservatively with diet modifications and monitoring. However, any severe obstruction or persistent symptoms generally require surgical intervention for relief.
Duodenal atresia is a congenital condition in which part of the duodenum is completely blocked or absent. It often occurs alongside Annular Pancreas, compounding feeding and digestive difficulties in affected newborns.
No. Polyhydramnios-excess amniotic fluid during pregnancy-can result from various fetal or maternal conditions. While it is one potential sign of Annular Pancreas, further testing is required to determine the exact cause.
Many infants with significant obstruction show symptoms such as vomiting and abdominal distension shortly after birth. However, some individuals have a milder form that may not be recognized until childhood or even adulthood, when digestive discomfort or nausea arises.
Yes. Surgical correction-often performed laparoscopically-is generally considered safe for newborns. Most infants recover quickly, resume feeding within days, and experience low rates of complications.
Recovery typically takes two to four weeks. Many patients begin eating small amounts by mouth within a few days post-operation and can gradually return to a normal diet as tolerated.
Some patients require follow-up visits, especially if symptoms persist or recur. However, most people who undergo successful surgery for Annular Pancreas experience long-term relief and do not need extensive ongoing care.
Yes. For mild cases or during postoperative recovery, smaller, more frequent meals and limiting high-fat foods can ease digestion and reduce discomfort.
